Description

Detailed Description of the Invention

  The present invention relates to an apparatus for enclosing a liquid in a synthetic resin pipe or a metal pipe and storing it in water or in water, and a water transportation method.

  Water shortages are serious in some areas, and transportation and storage of water is a problem. There are also transportation to areas where there is no storage space, and it is necessary to comprehensively solve transportation and storage methods. In the case of oil, there is a history, and storage tanks and storage locations have been established, but transportation and storage costs are still a problem. In addition, there are storage problems such as liquid chemicals.

  When storing liquids, large-scale construction work is being carried out to build a huge iron storage tank on land that has been reclaimed on the seashore at the coast. However, there are various problems that need to be solved before construction, such as suitable land, residents' consent, huge expenses, and cleaning of the tank.

  As for liquid transportation, we are currently using huge tankers. Tanker storage tanks must be cleaned when the content of the liquid being transported changes. Liquid transportation from tankers such as collisions and grounding becomes a problem during transportation. Regarding a water transport device using a tube, there is a method in which tubes are connected like a kite and towed by a ship in Japanese Patent Application Laid-Open No. 2003-154992 filed by the present applicant.

Problems to be solved by the invention

  Poor location requirements for establishing a storage tank at the coast, necessity of funding for the establishment of a large storage tank, fatal accidents when cleaning the storage tank, evaporation problems due to exposure to air, equipment for subdivision, storage There are various problems that cannot be solved by conventional techniques such as temperature management in the tank. Also in transportation, there are problems such as tanker costs, subdivision problems, storage tank cleaning, deterioration due to foreign liquid contamination, and spillage from tankers.

  In order to transport liquids over the sea, a method has been proposed in which a tube is filled with liquid instead of a tanker and is assembled like a kite to tow the sea. However, when a tube is used, there are problems such as toughness, durability, storage property, and difficulty in towing of the tube. For this reason, it is difficult to store the tube filled with the liquid on the shore after sea transportation. The bag-like liquid carrier is developed in water, most of the carrier filled with liquid, is indefinite, has a large resistance in water, and is unstable, so it is transported at a low speed of about 4 knots. In addition, there is a risk of the tube breaking, so it is not possible to berth directly on the quay, and it is necessary to transship to another liquid carrier offshore, resulting in increased costs and increased work time.

Means for solving the problem

  As described above, since the conventional techniques have problems in cost and convenience, the present invention solves the problems by using a synthetic resin pipe or a metal pipe. Both ends of the pipe are sealed to provide an injection / discharge hole and an air vent hole, and a liquid is injected into the pipe and stored on water or in water.

  When storing pipes on water, the pipes are stored in a frame to fix a plurality of pipes. The frame body is open at the top and is provided with a partition frame.

  In order to obtain buoyancy for water storage and transport, the air layer is usually left in the pipe without full liquid injection, but instability due to liquid flow in the pipe is avoided.

  As described in claim 2, both ends of a double pipe in which a fine pipe is inserted into a thick pipe are sealed, and an injection / discharge hole and an air vent hole are provided between the inner pipe and the inner / outer pipe. Buoyancy can be maintained even when the inner pipe is fully filled with the air layer between the inner and outer pipes. When storing a pipe containing a liquid in water, the buoyancy of the pipe is reduced when water is injected into the air layer, and the pipe is easily stored in water. When the water is discharged, the buoyancy can be recovered.

  As described in claim 3, a spiral pipe can be used. In this pipe, the pipe is spirally provided with irregularities, the inside of the pipe is sealed, and an air layer is provided on the outer convex portion. To determine the toughness of the pipe and the reduction of manufacturing cost by sealing the both ends of the spiral pipe, providing the inlet / outlet holes and air vent holes, and securing the buoyancy by using the air layer of the convex part of the sealed spiral pipe Can do.

  As described in claim 4, a ring pipe can be used. In this ring pipe, the pipe is provided with irregularities at regular intervals, the inside of the pipe is sealed, and an air layer is provided on the outer convex part. Using a ring pipe has advantages in terms of buoyancy, toughness, and cost, just like a spiral pipe.

  In order to store and transport a large number of pipes filled with liquid, an appropriate pipe storage device is required. Float on the sea by combining a frame containing pipes filled with liquid in parallel to create a huge floating island, submerged in water to effectively use the storage location, and tow the pipe together with the frame when transporting by sea Thus, storage space can be secured, stored, and transport costs can be reduced.

  In the frame of Claim 5, it becomes the shape which made the lower part of the side frame of the frame and the middle partition frame into the H type joint part, and made the upper part of the side frame and the middle partition frame into the C type joint part. Yes. The frames can be connected to each other by inserting the H-shaped joint portion into the C-shaped joint portion of another frame.

  In the frame of the sixth aspect, guide rollers are attached to the front and rear upper ends of the side frames of the frame, and the lower side frame is formed as a C-shaped rail. The guide rollers can be inserted into the C-shaped rails of other frames to easily connect the frames.

  When the buoyancy of the pipe is insufficient, a method of inserting styrene foam or the like into the pipe to assist in buoyancy can be used. In order to fix the pipe to the sea floor, there is a method of attaching a chain with a hook to the frame. In order to fix the frame body to the seabed, a method is also conceivable in which the base of the mesh created in accordance with the frame body is sunk on the seabed, the frame body is fitted on the base, and the upper part of the frame body is connected. As a merit of using a pipe for storing liquid in water or in water, the shape, length and thickness of the pipe can be selected, and since the change in water temperature is small, it can be stored in a certain temperature range. Since the required amount can be calculated by the number of pipes, there is no waste and work efficiency is increased. Individual pipes and frames can be transported by land.

  In the frame according to claim 7, since the frame that accommodates the liquid-filled pipe is solid and shaped, and the resistance of water is constant, hydrofoils are attached to the lower part of the front and rear of the frame. Therefore, it can fly on the water like a hydrofoil, and can use medium to high speed even if a small towed vessel is used. For this reason, it can respond to emergency transportation and disaster area support activities, reducing transportation and working time and reducing various costs.
